#134 Gastrointestinal neuroendocrine tumors: tumor characteristics and long-term clinical outcome in the German NET registry
Introduction: Prognosis of neuroendocrine tumors (NETs) has been difficult to predict due to heterogenous tumor biology, various classification systems, and lack of reliable and recent data due to the rarity of these tumors.
Conference: 7th Annual ENETS Conference (2010)

#213 Distinct Cut-Off Values of Ki-67-index for NET-Grading in a Large German Multicentrer Cohort
Introduction: Grading (G) of neuroendocrine tumors (NET) according to ENETS is based on immunhistochemical staining of Ki-67 antigen. Close margins between G1 and G2 NET often fail to differ in survival analysis.

#363 Clinicopathological characteristics are capable of predicting long-term outcome of gastrointestinal neuroendocrine tumours in Germany
Introduction: Neuroendocrine tumours (NET) are a rare and heterogeneous group of neoplasm. Throughout the last decades the classification of NET has been both difficult and incoherent. Therefore making prognostic straticifation often difficult.

#561 Determinants of Long-Term Outcome for Rectal NETs from a Large German Multicentre Cohort
Introduction: Neuroendocrine tumors (NET) of the rectum are a rare subgroup of NETs with mostly favorable prognosis. Some, however, tend to have a poorer outcome.

#562 Expression of Chromosome 18 Related Tumor Suppressor Proteins in Ileal Neuroendocrine Tumors
Introduction: The genetic alterations in ileal neuroendocrine tumors (iNETs) are poorly
characterized. The most frequent chromosomal aberration is the loss of one
chromosome 18 in iNETs, however, the relevance of this alteration is unclear.

#564 Genetic Alterations in Glucagon Cell Adenomatosis
Introduction: Glucagon cell adenomatosis (GCA) was recently recognized by us as a multifocal neoplastic disease of the endocrine pancreas unrelated to MEN-1. Multiple micro- and a few macrotumors are found on the background of a hyperplasia of glucagon cells. The disease may cause unspecific abdominal symptoms and only rarely a glucagonoma syndrome. Recently a mutation in the glucagon receptor (GCGR) gene was described in one GCA
patient.

#565 Proliferative Activity is Not Associated with Tumor Aggressiveness in Ileal Neuroendocrine Tumors
Introduction: The accuracy of the new WHO grading system for neuroendocrine neoplasms has not yet been validated for ileal neuroendocrine tumors (iNETs).

#700 Comparative Expression Analysis of Chromosome 18 Related miRNAs in Ileal NET with and without Chr18 Loss
Introduction: MicroRNAs (miRs) play important roles in many kinds of biological processes. Because the (partial) loss of one chromosome 18 (Chr18) is a frequent event in ileal NETs (iNETs), we assessed the potential deregulation of miR-expression in these patients.

#730 Loss of Chromosome 18 in Neuroendocrine Tumors of the Midgut
Introduction: The genetic alterations in neuroendocrine tumors (NET) of the midgut, in particular of the appendix (aNET), are poorly characterized. The most frequent chromosomal aberration in ileal NET (iNET) is the loss of one chromosome 18. The relevance of this alteration is unclear.

#742 Evaluation of Relevant Factors of Prognosis Among a Large German Multi-Centric Cohort–Results from the German NET Registry
